I've smoked more than a few newly-low-hanging branches riding during/after wind storms.

And there was a telephone cable hanging neck-high over a public road on my ride in of last week. It looped back up high enough over the middle of the road so that the cars didn't hit it. I have no idea how it didn't catch on any trucks for a full week.

No helmet light though. I have enough stuff strapped on my head this time of the year.
